 		 #85376 - Russel
Responding to: ???'s previous message
I persnally DO hate what these "Ayatollah/politician"s are doing in Iran and to her glorious land. I strongly condemn their activities.

BUT

Craig said:
Lest the previous two messages be misunderstood, they were tounge-in-cheek humor. Please don't take them offensively.

Is that it? "misunderstood"? Is that all you can say? Are you not forgetting something? Is it not a "proffessional" forum? Or Russel's long term membership implies the right to be so funny? I'm afraid I shall never ever tolerate such sarcastic -not deceptive- attitudes. It's not funny. It's what goes through their minds that comes out of their mouth. It unexpectedly reveals the assumptions they made as default. It's not the words that is sarcastic, it's Russel's attitude. I expect their strict apology and your reevaluation of these message.
